3 Claims.

This invention relates to patterns and more particularly to patterns used in cutting shoe upper blanks from a leather skin or other shoe upper material.

It frequently happens that shoe upper blanks for shoe uppers of various styles have the same peripheral contour but differ from each other in the provision in the different blanks of various ornamental or other cut-outs. It was, therefore, necessary hereto to provide different patterns for use in cutting blanks having different ornamental cut-outs, respectively, although in other respects the blanks may be the same. As the same style is cut in a range of sizes, this necessitated the provision of sets of the different patterns, and since more than one set of patterns for each style is required for adequate production purposes, it is readily appreciated that the cost of the patterns may mount to a high level.

The primary object of the present invention is to obviate the above described disadvantages and in particular to provide a pattern which is not limited to one style but can be used in cutting shoe upper blanks of various styles in respect to the ornamental or other cut-outs provided in different blanks, respectively.

This object of the invention and objects ancillary thereto will be understood more fully from the following description considered with reference to the accompanying illustrative drawing.

In the drawing:

Fig. 1 is a plan view of a pattern embodying the present invention;

Fig. 2 is a sectional view on the line 22 of Fi 1;

Fig. 3 is a plan View of a removable part of the pattern shown in Fig. 1;

Fig. 4 is a sectional view on the line 4-4 of Fig. 3;

Fig. 5 is a view similar to Fig. 3 showing the part provided with a different form of pattern cut-out.

Referring now more particularly to the drawing, the pattern I0 embodying the present invention comprises a flat plate l2 formed of cardboard or other suitable material and having a knife-guiding edge constituted by a sheet metal edge-binding strip It extending completely around the peripheral edge of the pattern. As here shown pattern I0 is shaped to the contour of the shoe upper blank to be cut from the leather skin or other sheet of shoe upper material, said blank being for a pump or similar low shoe.

In accordance with the present invention, pattern I0 is constructed in such manner that with a slight change, easily effected, it can be used for cutting shoe upper blanks having any number of different shaped cut-outs which may remain open in said blanks or which may be filled with ornamental inserts. For this purpose the blank l2 of said pattern is provided with an opening "5 in which may be fitted any one of a number of auxiliary plates, for example, the plate I8 shown in Figs. 1 and 3 or-the plate lBa shown in Fig. 5, said auxiliary plates being preferably formed of sheet metal. It will be understood plates l 8 and la are merely illustrative of a number of plates which may be interchangeably fitted in plate I2 of pattern In. It will be understood also that said auxiliary plates may be fitted in patterns of different sizes since the cut-outs to be provided in blanks of a range of difierent sizes may be of the same size. The cut-out openings in the auxiliary plates may vary widely in configuration, said cut-out openings indicated at 20 and 20a in plates l8 and Mia, respectively, being merely illustrative.

In Fig. 1, the auxiliary plate is shown fitted in position in the forward vamp portion of the pattern centrally between the outer side edges of the pattern, but it will be understood that plate [2 of the pattern may have the plate-receiving opening l6 positioned difi'erently, and further it will be understood that plate 12 may be provided with more than one plate receiving opening so that the same may be used for providing shoe upper blanks of the same configuration with a plurality of cut-outs or with one or more cut-outs in various predetermined positions therein. As here shown, the auxiliary plate is provided with a pointed portion 22 and with an indicator line 24 to aid the shoe cutter in positioning the pattern in cutting the blank of shoe upper material. It will be understood that the auxiliary plate fits removably in the opening l6 therefor in the pattern, the non-circular peripheral edge 26 of said auxiliary plate engaging the non-circular peripheral edge of opening 16, and that the edge 28 of the opening in the auxiliary plate is used as a guide for the shoe cutters knife. While the auxiliary plates indicated at l8 and lSa are illustrated in conjunction with a pattern of one configuration, it will be understood that said auxiliary plates can be used with patterns of other configurations whereby shoe upper blanks of different peripheral edge contours may have the shown or described are well adapted to accomplish the objects of the present invention. It will be understood, however, that while I have shown and described the preferred embodiment of my invention, the latter may be embodied otherwise than as herein shown or described and that in the illustrated embodiment certain changes in the details of construction and in the arrangement of parts may be made and will occur to skilled artisans in view of the present disclosure. Therefore, I do not wish to be limited tothe invention as herein illustrated or described except to the extent which may be required by the scope of the appended claims.
